To all 'wim/m, it mayoomern:

Be it known that'l, CHARLES T, Sonoran, al citizen of the United States,residing at Media', in the county of Delaware and State of Pennsylvania,have invented a certain new and useful Improvement in Shock-Alosorbersfor Vehicles, of which the following is a full, clear, and exactdescription.

The object or" this'invention is to provide a shoclr absorber forvehicles ot simple and durable construction, and effective in operation,ant1 which is particularlyv designed tor use in connection with theelliptic springs ot automobiles, for the purpose of minimizing the e'ectof the shocks to which such vehicles are subjected in traveling overrough and uneven roads.

The invention consists in a shock absorber Comprising a spiral spring orsprings and means for connecting and supporting the same between thescrolls or pivotal connections ot the ordinary elliptic spring, allsubstantially as l Will proceed now more pan ticularly to set forth andfinally claim.

'in .the accompanying drawings, illustrating the invention, in theseveral gures ot which like parts are similarly designated, Figure l isva side elevation, partly in section, showingA the invention applied toa semi-elliptic spring. Figs. 2 and 3 are an f erid view and a sideelevation, respectively,

orne larger scale, ot the lett-hand spring connection of Fig. l. F ig.is an elevation on a larger scale ot the sprino connection at theright-hand side ot Fig. l, with its swivel nut detached. Fig. 5 is anend vieW on a larger scale of the tube connection at vthe right-hand endpivotal connection of the elliptic spring. Fig. 6 is an elevationshowing the shock absorber applied to the spring at the front end of anautomobile frame and showing the shoolr absorber spring incased.

As shownr in Fig. l, l is the main spring,

fand as herein shown, it is ot the 4semi-elliptic t e havin at its oposite ends the .1 i pivot or scroll connections 2 'and 3, and

vadapted to be connected with the vehicle in any suitable or usualmanner.

Connected with the scroll end 2 ot the elliptic spring by means ot thebolt e, is a casting 5, comprising an eye 6 and a head 7. The head 7 isprovided with a [lange 8, and beyond said flange with. spiral groove 9to receive the end coil o t spiral spring to be referred to, and beyondsaid speeiaeation of Letters raient.

spiral groove with a stepped or shouldered portion l0 to torni seats forthe spiral springs to be referred to. l casting ll, having ascrewthreaded socket l2 and an offset eye 13, is connected with theopposite scroll 3 of the main spring l, by means of the pivot bolt lil.Fitted in the screwthreaded socket l2 oit the casting 1l is a tube l5,provided at its free end 'with a scrcwthreaded portion i6.

A rod l7 fitted into a screvvthreaded socket 1S in the head 7 is adaptedto looselyv lit within the tubel. The tube l5 and rod 17 when thusfitted. together and connected to opposite scrolls of the ellipticspring l, are ot' sutlicient length to span the distance between saidscrolls, 'the tube l5 terminating Within a short distance ot the innerend et the casting 5, and having loosely mounted thereon collar 19,suitably hollowed out at 20, vto receive a swivel nut 2l, adapted to befitted upon and engage the screwthrcaded portion 16 ot the tube l5. Thecollar 19 is also provided With a spiral groove 22 to receive the endcoil of the spiral spring to be referred to.

Arranged between the casting 5 and the collar i9 is a spiral spring 23,with its end coils engaging and securely held by the spiral grooves 9and 22, respectively, in the casting 5 and collar 19, the coils of thespring 23 surrounding the telescoping tube l5 and rod 17. Preferably, asecond and smaller spiral spring 24 is arranged upon the telescopingtube 15 and rod 17 within the spring 23, and having its ond coilsengaging the casting 5 and collar ll), respectively.

As one illustration of the appl'caton of the invention, l have shown inFig. (S the shock absorber applied to a semi-elliptic spring attached tothe front end oi an automobile,l trame. ln said figure, 25 is the frarneg and it will be. observed that the elliptic spring is rigidlyattached to the 'trontl end 26 ot' the fra-nie 25 and at its other endis connected to the traine 25 by means ot a swinging link 27, the shockabsorber being attached to the outside of the semi-elliptic springthrough its castings 5 and ll., by means of the pivot bolts 28 engagingsaid castings and the end scrolls of the elliptic spring. By thisarrangement, observed that the attachment of the spring and its shockabsorber at the trent ot the automobile will not in any .vay interfereit will be CIT llt)
